摘　　要：针对大港沈家铺油田注入能力下降的问题,本文先进行结垢预测,再通过室内静态评价实验和动态评价实验以及岩心流动实验,验证预测结果,通过对结果的分析可得到注入水和储层流体的配伍程度及注入水和地层水混合后对岩心渗透率的影响。结果表明:大港沈家铺128区和109-1区的注入水与地层水混合后有结垢趋势,产生的无机垢对储层具有堵塞伤害性,笔者建议油田采用防垢措施,改善水质。This paper mostly aim at Dagang Oilfield Shenjiapu injection ability falling problem,first scaling prediction,and then through experimental evaluation of indoor static and dynamic evaluation of core flow experiments,Study the compatibility between inject fluid and reservoir fluids and the influence of a mixture of formation water of permeability of the core.The results show that Dagang Shenjiapu District 128 area and the injected water and formation water mixed trend scaling,norganic scaling of reservoir are jam harmful,Suggest oilfield use antiscale measures to improve water quality.
